The iody lot'"thesupporting device F, in

addition to. the bar 70",: just referred to, -consists of a forked head, the two'. tine members Y 72 Aand 73 whereofv are one above the other, and friction-rollers 74, mounted to. tiirn at the outer ends of the said tine members, as is clearly shown iii Fig. 1. A bar 75 is pivoted between the tine members 72 and 73 of the supporting device` F, and the bar member is provided with anoutwardlyfextending arm 75, whicliearries thefriction-roller 76,10- cated betwecn the friction-rollers 74 on the tine members. vThe friction-roller 77 isiiormally carried out of vertical alinement withv the roller 'by means of a spring 78, which bears againstthe body of the sup ortingj'device Fat one side and against t e'thumbieee 79, which extends from, the bar 76.

2. In a multiple-drill socket, a frame, a standard for supporting the frame, an arm -adjustably connected with the frame, a body adjustably connected with the arm, a forked 'extension from the body, the tines thereof' engaginga oove in the standard and a tension-contro ed pivoted member between the tines ofthe fork extension and also engaging the groove.

3. In drill-sockets, a .frame and a support for the frame, 'the said support consisting of .an arm adjustably connected with the frame, A abody adjustably connected with the arm, a

forkedy extension-from the body, a tensioncontrolled pivoted member between the tines of the fork extensionQriction-rollers carried at the outer extremities of the tine members v of the fork, and a'fric-tion-roller carried by the said member, ivoted between the tine members ofthe for the intermediate roller being normall out of alinement with the outside rollers, ut all the rollers being practically in alinement when the support is 1n operation.

4. In a drill and in combination, a standard provided With a vertical groove, a frame supported by the standard and comprising -upper and lower... lates .each having an arc- 4shaped slot para el and in alinement with the slot in the opposite plate, a tube having one end slotted and internally screw-threaded, and having a tubular head on the o posite end arranged between the lates o the frame, a bolt traversing the hea and the varcshaiped slots, a rod telescoped Within the tube an provided with a nut for enga ing the screw-threads on the bolt, a forked ead on the outer end of the bar, friction-rollers on the tines ofthe forks for engagin the groove of the standard, a bar pivoted etween the tines and rovided on its outer end with a `friction-ro er also engaging the groove, and a spring normally maintaming the roller on the bar out of alinement with the rollers on the tines.
